On the other hand, however, the history that has led to the triggering may be of interest and be included in the optional data storage by a corresponding storage regime.
- the evaluation device 13 determines that the current driving state requires electronic activation of the binding, it generates a triggering signal T, which is fed to the actuator 15 and activates or triggers it.
- the actuator 15 comprises a drive and said output member 18.
- the drive comprises a sleeve-shaped guide structure 16 for the output member 18 and an ignitable propellant charge 17 by the trigger signal T , a current or voltage signal, is ignited and when driven, the output member 18 in the guide structure 16 in a direction of action W to maximally against a stop, which is formed in the example of the guide structure 16, propelled.
- the actuator 15 may be formed in particular as a removable cartridge. After triggering a new cartridge, a new actuator 15 is inserted and connected to the evaluation device 13, preferably by inserting.
- the actuator 15 may be constructed according to a conventional rifle cartridge, the output member 18 replaces the projectile, but with the difference that the output member 18 is tied up in the direction of action W due to the limitation of the release movement, so to speak represents a tied projectile.
- the path length traveled by the output member 18 in the direction of action W when triggered, is a few millimeters.
- the path length is preferably at least 3 mm, more preferably at least 5 mm.
- the pathlength is preferably at most 20 mm, more preferably at most 15 mm.
- the actuator 15 is supported against the direction of action W on the housing 6.
- the reaction force to be absorbed when triggered is therefore transmitted via the housing 6 into the fastening engagement of the connecting device and received in the fastening engagement.
- a power source 19 is further arranged, which supplies all components within the housing 6 with electrical energy, as far as the respective components require electrical energy.
- the energy source 19 is rechargeable and may be externally charged via a charging port 20, which is a galvanic or preferably an inductive port.
- the controller 10 has the capability of data communication with an external device, preferably a standard computer such as a laptop.
- Part of the trip unit 5 is therefore a data interface 21, via which data from outside the trip unit 5 in a memory of the controller 10, for example, in the data memory 14, read and / or can be read from the memory in question.
- the data interface 21 may advantageously be used for wireless data communication, i. for wireless transmission and / or reception. In principle, however, it can also be an interface for galvanic contact instead, which however entails the risk of contamination and damage. Therefore, the trip unit 5 advantageously has no or as few galvanic interfaces as possible to the outside.
- the binding may in a further development be arranged for communication with an associated second binding in order, for example, in the case of an electronic triggering, to trigger the other, associated binding in a synchronized manner.
- an associated second binding for example, in the case of an electronic triggering
- a transmitter 22 and a receiver 23 for wireless communication with a dedicated trip unit of the other assigned Binding can be arranged. If the evaluation unit 13 generates a triggering signal T, this signal or a signal derived therefrom is transmitted via the transmitter 22 and received by the receiver 23 of the associated other binding or triggering unit, whereupon the associated triggering unit 5 also triggers.
- the trip unit of the associated other bond may correspond to the trip unit 5.
- the tripping unit 5 has the same functionality as the tripping unit 5 and is advantageously provided with a corresponding connecting device like this as a quick-change unit.
- the two trip units are identical or at best differ by assignment to a left ski and a right ski.
- the actuator 15 As from the synopsis of FIGS. 1 and 2 can be seen, form the actuator 15, more specifically its output member 18, and the coupling member 7 with each other a coupling interface over which acts in the case of triggering the actuator 15 on the coupling member 7 and thereby triggers the binding.
- the coupling interface is formed as a pure stop contact of the output member 18 and coupling member 7.
- the actuator 15 via its output member 18 with the coupling member 7 in a coupling engagement, which is based only on stop contact in the direction of action W.
- the stop contact may also be in the idle state, ie, prior to triggering or non-triggering. Instead, the output member 18 and the coupling member 7, facing non-triggering in the direction of action W, but opposite each other by a short distance physically separated.
- the output member 18 In the case of triggering the output member 18 is driven in the manner of a ram in the direction of action W, which coincides as preferred with the longitudinal direction X, against the coupling member 7 and drives this in the direction of action W to the rear.
- the release movement of the output member 18 is transmitted via the coupling member 7 and the further coupling member 9 on the rear holding unit 2.
- the coupling of output member 18 and holding unit 2 formed by means of the coupling members 7 and 9 is, in preferred embodiments, axially pressure-resistant so that it moves away from the front holding unit 1 by a path length corresponding to the path length of the tripping movement of the output member 7. If there is a clear distance between the output member 18 and the coupling member 7 in the rest state, the path length by which the rear holding unit 2 is moved is reduced by the clear distance.
- the rear holding unit 2 is pressed as usual in ski bindings by a starting spring in the direction of the front holding unit 1 to a maximum against a stop.
- the starting spring serves to compensate for bending deformations experienced by the gliding board during travel relative to the shoe.
- This arrangement can advantageously be used to loosen the holding engagement of the holding units 1 and 2 with electronic triggering.
- the output member 18 presses when triggered the rear holding unit 2 against the restoring force of the starting spring to the rear, away from the front holding unit 1.
- a short stroke movement is sufficient to loosen the retaining engagement sufficiently so that the shoe is released from the binding.
- the forces still required for the release can correspond to the forces typically set for childbinding.
- the predetermined by the actuator 15 path length of the release movement of the output member 18 is preferably such that adjust such balance of power in complete execution of the release movement.
- FIG. 3 shows a binding in a longitudinal section, which is modified with respect to the coupling of trip unit 5 and rear support unit 2. 4, the release spring of the holding unit 2 is designated.
- the holding unit 2 is guided in the longitudinal direction X of the binding guided back and forth.
- a spring 30 acts on the holding unit 2 with a spring force acting on the holding unit 2 in the direction of the in FIG. 3 not shown front holding unit acts.
- the spring 30 thus biases the holding unit 2 in the retaining engagement with the shoe and allows bending deformations of the ski below the shoe.
- the spring 30 is supported at one end on a first spring bearing 31 and at the other end on a second spring bearing 32 and is clamped between the spring bearings 31 and 32 with a biasing force.
- the first spring bearing 31 is, apart from the case of a release by means of the trip unit 5, relative to the base structure 3, in the mounted state relative to the ski, axially immovable.
- the second spring bearing 32 is immovable relative to the holding unit 2.
- the coupling of coupling member 7 and further coupling member 9 may also be designed so that the coupling member 7 when triggered the further coupling member 9 via a corresponding articulated connection, such as a thrust connection or a lever connection, moves in the appropriate direction to the spring force to reduce the spring 30.
- the first spring bearing 31 is formed by a part manufactured separately from the further coupling part 9 and is connected to the further coupling member 9 in a preferably releasable fixing engagement, in which it is axially immovable relative to the further coupling member 9.
- the further coupling member 9 has a coupling portion 19 in which the spring bearing 31 with the further coupling member 9 is in the fixing engagement.
- FIGS. 4 and 5 show a coupling means 7 and 9 comprising coupling means for coupling of tripping unit 5 and holding unit 2.
- FIG. 4 is the coupling device in a plan view of the bottom and in FIG. 5 shown in a side view.
- the coupling member 7 is guided by the guide device 8 in the longitudinal direction X movable. When triggered, it acts in the direction of action W on a securing element 25, which the further coupling member 9 against the force of the spring 30 in a Secures securing and thus axially fixed relative to the base structure 3 of the bond.
- a securing spring 29 holds the securing element 25 in the securing engagement.
- the securing element 27 is a lever rotatable about an axis of rotation 26.
- the axis of rotation 26 is as preferred, but only by way of example, parallel to the vertical axis Z (FIG. FIG. 3 ).
- the securing element 25 has, starting from the axis of rotation 26, a first lever arm 27 and a second lever arm 28.
- the coupling member 7 acts on triggering on the first lever arm 27.
- the locking spring 29 acts on the second lever arm 28. It is as preferred, but only as an example formed as a compression spring, so exerts on the second lever arm 28, a pressure force.
- the force of the locking spring 29 is sufficiently high to ensure the securing engagement in all driving conditions occurring in practice.
- the force of the locking spring 29 is overcome in electronic tripping when the actuator 15 ( FIG. 1 ) Presses in the event of triggering in abutting contact against the coupling member 7 and this moves the securing element 25 against the force of the securing spring 29 from the securing engagement.
- the further coupling member 9 has a hook-like extension 9a for the securing engagement, with which it engages behind a pawl of the securing element 25.
- the securing element 25 is rotated so far around the axis of rotation 26, that the opening of the pawl longitudinally to the rear, so that the further coupling member 9 can move axially from the pawl open to the rear.
- the spring 30 exerts via the first spring bearing 31 on the further coupling member 9 in the longitudinal direction X of the front holding unit directed away spring force. This spring force also acts in the securing engagement, but is compensated by the securing spring 29. When triggered, however, the spring force of the spring 30 causes the extension of the further coupling member 9 from the then opened securing engagement.
- the securing element 25 forms the coupling member, which forms the coupling interface with the actuator 15.
- the actuator 15 replaces the above-described coupling member 7.
- FIGS. 4 and 5 is indicated accordingly that the coupling member 7 can be replaced by the actuator 15.
- the actuator 15 acts on triggering directly on the fuse element 25, which thus assumes the function of the coupling element described so far.
- the rotary guide or rotary guide occurs about the axis 26.
- the housings 6 and 8 are preferably shaped adapted to each other, so that the housing 6, the actuator 15 and the housing 8, the region of the locking engagement of the Secured fuse element 25 formed coupling member with the further coupling member 9.
- FIG. 4 are a shape according to adapted housing 6 dashed and a dotted shape adapted housing 8 indicated by dotted lines.
- the binding can be set back to the ready to drive state after an electronic triggering, even if the triggering device comprises an actuator 15 pyrotechnic type.
- the bond can thus be used after an electronic triggering as a conventional bond, without replacing the actuator 15 or, in the case of a resettable actuator, this must be returned to the initial state.
